I have a phenom II 940 over clocked to 3.67ghz at 1.392v (204*18) will it be advisable to try and get it at any higher speeds? I have reached 3.8ghz but with my voltage maxed out. I also want to buy a hd 6950 within a couple of weeks. what do you guys think is there a processor upgrade required? I have a cooler master gladiator 600 case.
